I had to buy a new mobo, my old one broke. The new mobo has on the box all this DualBios talk on it. So I bought it, installed it, and I put a fresh copy of xp pro on it. No where did I have to mess with the BIOS like I see so many people dealing with, just as easy as can be. If my pc worked with the first BIOS why do people mess around with it because I always read people having issues with it and all the lingo that goes along with it..such as flash and whatever else. What good is a a dualBIOS option let alone addign a new version of a bios???

The concept of Dual BIOS is effectively an attempt to prevent the board being toast if you were to flash it with a corrupt file or (God forbid) the wrong file for that board.
By having two copies of the BIOS, effectively, one of which is a back-up that you cannot flash, the idea is you can recover easily.

Here's a flowchart of how it works:

As to "messing" with the BIOS, the default options work fine for most people. However sometimes you have to update it particularly if you want to use a processor that came out after the board was made.
